Abstract
An impact rapping device includes a stationary anvil integrated with a surface to be rapped, the anvil having a hammering axis perpendicular to the surface to rapped, a hammer arranged to move coaxially with the hammering axis, to hit an impact surface of the anvil, and a device for moving the hammer. The anvil and the hammer form a compact unit, which can be assembled in any position. The hammer is supported to lean on the anvil in such a way that the position of the hammer automatically follows changes of place or position of the anvil, and so that the hammer can move only parallel to the hammering axis.

An impact rapping device comprising:
- a stationary anvil integrated with a surface to be rapped, the anvil having an impact surface and a hammering axis perpendicular to the surface to rapped;
- a hammer, arranged to move coaxially with the hammering axis, to hit the impact surface of the anvil;
- a moving device for moving the hammer;
- and
- at least one sliding element arranged between the anvil and the hammer,
- wherein the anvil, the sliding element, and the hammer form a compact unit, which can be assembled in any position, and the hammer is supported to lean on the anvil, with the at least one sliding element arranged therebetween, in such a way that the position of the hammer automatically follows changes of place or position of the anvil, and so that the hammer can move only parallel to the hammering axis.
